摘要： A solid state light having a solid state light source such as LEDs, a light guide having an enclosed interior volume such as a bulb shape without vents, and a thermal guide. The light guide is coupled to the light source for receiving and distributing light from the light source. The thermal guide is at least partially contained within the interior volume with an air gap between a portion of the thermal guide and the light guide. The thermal guide provides for thermal conduction from the light source and dissipating heat through convection and radiation for cooling the light.
